The popularisation of digital technologies and their relevance in everyday communicative interactions is a reality that has aroused the interest of the scientific community. An approach from the point of view of emotions, understood as a predominant value of contemporary society, allows us to map, as I have done throughout these pages, a vibrant, broad and complex field of research as part of Media and Communications Studies, where different theoretical and methodological approaches converge. Two major areas of study are noteworthy in this field. On the one hand, there are emotions related to the use of technological devices (including the mobile phone, which is the most emotionally charged, and consequently, has been analysed in greatest depth by researchers). On the other hand, there is the digital sphere—the realm that is accessed through screens—as a space where the affective dimension of technology users emerges and is expressed.
